After having a revelation one night in a pub about how he could help Bosnian refugees, Scottish farmer Magnus MacFarlane-Barrow went on to quit his job and dedicate himself full-time to helping people in need.
MacFarlane-Barrow founded Mary's Meals, an organization that feeds more than 400,000 hungry schoolchildren in Malawi, Haiti and other developing nations around the globe.
CNN has honored MacFarlane-Barrow as a CNN Hero.
